Iceland volcano eruption threat high as workers race to shield power plant – live

Authorities in Iceland are racing to build defence walls around the Svartsengi geothermal power plant, located just over 6kms (4 miles) from Grindavik.

It comes as the probability of an eruption remained high despite a decrease in seismic activity, the Icelandic Meteorological Office said.

Authorities said they were preparing to construct a large dyke designed to divert lava flows around the Svartsengi geothermal power plant.

Justice minister Gudrun Hafsteinsdottir said equipment and materials that could fill 20,000 trucks were being moved to the plant, according to state broadcaster RUV.

Construction of the protective dyke around the power station was awaiting formal approval from the government.

A spokesperson for HS Orka, operator of the power plant, said it supplies power to the entire country, although a disruption would not affect power supply to Reykjavik.

Authorities in Iceland have elevated their aviation alert to orange after increasing concern about a potential volcanic eruption.

Volcanic eruptions present a significant aviation hazard as they can release highly abrasive ash into the upper atmosphere, posing the potential for engine failure, impairment of flight control systems, and diminished visibility.

A major eruption in Iceland in 2010 caused widespread disruption to air travel between Europe and North America, costing airlines an estimated $3bn as they canceled more than 100,000 flights.

Iceland’s Met Office confirmed that the probability of an eruption remained “unchanged” and “gas does not appear unless magma is high in the earth’s crust”.

Meteorologists continue to keep a close eye on the region which was evacuated earlier on Tuesday after high levels of sufur dioxide were detected.

Over 700,000 people visit the Blue Lagoon every year, one of Iceland’s top tourist attractions. However, it has been shut until Thursday amid risks of a huge volcanic eruption that could obliterate the town.

Countless couples have had to cancel honeymoons and holidays to the romantic venue which features natural thermal springs and pearly blue water.

The town of Grindavik has been evacuated amid rising risks of an eruption.

The Australian government has issued a travel advisory for people, asking them to avoid areas near volcano eruption sites and in areas around the Reykjanes peninsula.

“Avoid areas near volcano eruption sites and areas close to mountains with steep slopes on the Reykjanes peninsula due to the danger of falling rocks,” the government’s Smarttraveller website said in an update.

“Volcanic and seismic activity around Mt. Thorbjörn, 40km southwest of Reykjavik and near the Blue Lagoon and Keflavik International Airport, has increased.”

The town of Grindavik could be obliterated in an eruption, Lydia Patrick reports.

The country has been shaken by more than 2,000 small earthquakes in the past few days, prompting fears that the tremors could disrupt the Fagradalsfjall volcano on the Reykjanes peninsula in the southwest of the country.

Thousands have been told to evacuate Grindavik as a precautionary measure, while a magma tunnel stretches below the surface. If an eruption occurs in or close to the town, the consequences will be devastating, volcanologist Armann Hoskuldsson warned.

He told state broadcaster RUV: “This is very bad news. One of the most serious scenarios is an eruption in the town itself, similar to that in Vestmannaeyjar 50 years ago. This would be much worse.”

Ragga Agustsdottir, who lives close to Grindavik, said residents were fearful of what could happen if an eruption struck. “The scenario on the table now is that it will happen in or just north of the town of Grindavik. There’s no good option here,” she told The Independent.

The Icelandic Meteorological Office said on Saturday there was a “considerable” risk of an eruption on the Reykjanes peninsula because of the size of the underground magma intrusion and the rate at which it was moving.

The construction of lava barriers has begun around Svartsengi power plant and the Blue Lagoon.

The walls are being built to shield the power plant from being damaged and destroyed in the event of an eruption.

Iceland’s Parliament approved a bill just before midnight last night to enable the building of lava barriers, which will be financed through a tax hike, according to Iceland Review.

Threats of an eruption have caused thousands of earthquakes in the last few days, but Mark Gongloff for Bloomberg writes that fossil fuels are still a hundred times more harmful.

In an attempt to clarify rumours circling on social media, the journalist confirmed that planet-warming gases could be emitted. But their scale and content would not be as harmful as the equivalent toxins emitted through human consumption and waste.
